Criminal Psychology: How Criminal Minds Think

Introduction: Criminal Mind

Crime cannot be understood as merely an unlawful act; rather, it is a complex human phenomenon that emerges from the depths of the human psyche, where desires, conflicts, social pressures, and biological structures intertwine. Criminal psychology does not only ask “what happened?” but goes beyond it to a deeper question: “why did it happen?” and “how does the offender think?” The criminal mind is not a mysterious entity separate from the rest of humanity; rather, it is an extreme reflection of the same tensions experienced by ordinary individuals, but expressed through a different path.

From this perspective, many thinkers throughout history have attempted to interpret this mind, each from their own angle, offering views that range from biological determinism to deep psychological explanations, and extending to social analysis and philosophical critique.

However, before delving into the depths of this complex world, fundamental questions impose themselves with urgency: How is the criminal mind actually formed? Is a person born with seeds of deviance within them, or does society plant them through hidden pathways? Can a clear line truly be drawn between the “ordinary person” and the “criminal,” or is the difference sometimes no more than a moment of weakness or a harsh circumstance? And if criminal thinking is the result of a complex interaction between psyche and environment, are we dealing with a phenomenon that can be controlled, or a human condition that repeats itself in different forms across time and space?

Based on these questions, and in order to address this topic, we will adopt an analytical framework that seeks to deconstruct the phenomenon of the criminal mind through interconnected axes. We begin first with the study of biological determinism, which attempts to explain crime through the individual’s innate constitution. We then move second to analyze psychological conflict and hidden motives that govern human behavior internally, before addressing third the role of social learning and environment in shaping criminal thinking. Fourth, we will discuss the social dimension of conflict and inequality, leading fifth to the idea of multiple causation and the complexity of the criminal phenomenon, and finally we will examine criminal determinism between freedom and determinism to understand individual responsibility and its limits.

First: Biological Determinism and the Beginning of Understanding the Criminal Mind

The Italian physician Cesare Lombroso is considered one of the first to attempt to explain the criminal mind from a biological perspective. He argued that the criminal is born with innate characteristics that distinguish them from others, and that they are closer to the “primitive human” in terms of physical and mental constitution. In his view, criminal thinking is not so much the result of a conscious decision as it is a reflection of a deviant biological nature.

However, despite its historical importance, this perspective raises a deep philosophical problem: if a person is biologically compelled toward crime, where does their moral responsibility lie? And can they be held accountable for what they did not freely choose?
This question later pushed other thinkers to move beyond this reductionist explanation and to explore the depths of the psyche rather than the surface of the body.

The concept of biological determinism cannot be separated from the scientific context in which it emerged. The nineteenth century witnessed the dominance of positivism, which sought to explain human phenomena using the same tools applied in the natural sciences. Within this framework, Lombroso’s goal was not merely to describe the criminal but to discover “natural laws” governing criminal behavior. This scientific ambition, despite its reductionism, reflects a deep human desire to remove the mystery from evil and transform it into a phenomenon that can be understood and explained.

Yet this biological explanation raises another issue related to the danger of classification, as it may lead to stigmatizing certain groups based on outward traits, potentially creating a kind of “self-fulfilling prophecy,” where an individual is treated as a potential criminal and thus moves toward that path. Here, science shifts from being a tool of understanding to a tool of domination, which led many critics to reject this approach as inhumane.

Nevertheless, it cannot be denied that some modern studies in neuroscience have revived aspects of biological determinism in a more precise manner, by linking aggressive behavior to brain or hormonal imbalances. The key difference, however, is that these studies do not completely deny the role of will; rather, they suggest that biology creates predispositions, not absolute determinism, thereby restoring balance between science and ethics.

Second: Psychoanalysis and the Conflict of Hidden Motives

With Sigmund Freud, the interpretation of the criminal mind entered a more complex stage. Criminal behavior was no longer seen merely as a result of external or biological factors, but as an expression of internal conflicts between the three components of the psyche: the Id, the Ego, and the Superego.

Freud argued that crime may result from the dominance of the “Id,” which represents primitive desires and instinctual drives, alongside the weakness of the “Superego,” which represents conscience and moral values. In this case, the individual becomes unable to restrain their desires, and their behavior deviates toward crime.

However, Freudian analysis goes further, linking some crimes to unconscious guilt. According to him, some individuals commit crimes as a means of seeking punishment, in an unconscious attempt to rid themselves of this feeling.

This perspective opens a profound philosophical question: Is crime always an expression of evil, or is it sometimes a troubled attempt to restore a lost psychological balance?

Psychoanalysis does not view crime as an isolated act, but as part of a long psychological history beginning in childhood. Early experiences, especially those related to parental relationships, play a crucial role in shaping an individual’s psychological structure. Severe repression, neglect, or violence may lead to the formation of a disturbed personality unable to adapt to social norms, finding in crime a means to express internal conflicts.

In this context, Sigmund Freud introduced a tripartite model of the human psyche consisting of the Id, Ego, and Superego, offering deep insight into criminal thinking. The Id represents the reservoir of primitive instincts, where repressed desires and innate drives seek immediate gratification without regard for values or laws. The Ego acts as the mediator attempting to reconcile these desires with reality, while the Superego represents the moral conscience imposing constraints and standards. When imbalance occurs—such as the dominance of the Id or the weakness of the Superego—the individual may be driven toward deviant behavior, not out of pure evil, but due to an internal collapse in psychological regulation.

This internal conflict is not always conscious; it often occurs at a hidden level beyond the individual’s awareness. In many cases, the criminal does not see themselves as a criminal, but as a victim of uncontrollable desires or as someone justified in their actions. Here, the Ego becomes crucial: if strong and balanced, it can regulate the Id and soften the harshness of the Superego; if weak, it fails in this role, opening the door to criminal behavior as an alternative solution.

From a more human perspective, one can speak of the “emotional criminal,” an individual who does not commit crime through planning or cold calculation, but under the influence of intense emotions such as anger, jealousy, or overwhelming love. This type of crime reveals that no matter how conscious a person is, they may collapse under emotional pressure, where the Superego temporarily retreats and the Id asserts full control. In such moments, criminal action is not rational but an emotional explosion reflecting fragile psychological balance.

Benigno Di Tullio focused on these aspects, attempting to develop an integrative view combining psychoanalysis with biological and social factors. He argued that the criminal is not the product of a single factor, but a personality shaped through complex interaction between internal predispositions and external conditions. He also emphasized the idea of “criminal constitution,” suggesting that some individuals develop psychological structures that make them more prone to deviance, especially if not socially and psychologically supported early on.

Di Tullio stressed that understanding the criminal requires moving beyond superficial judgment of the act to deep analysis of the personality, with all its contradictions and conflicts. The criminal, in his view, is not always devoid of humanity, but may be someone who failed to find healthy ways to express themselves or achieve psychological balance, thus choosing—or being pushed toward—a deviant path.

In light of these perspectives, psychoanalysis becomes not only a tool for explaining crime, but also for reconstructing a more human understanding of the criminal, as a being engaged in deep internal conflict, where opposing forces struggle within, and where instinct may overcome morality, or emotion may overpower reason, in a decisive moment that alters the course of life entirely.


Third: Social Learning and the Criminal Mind as a Product of the Environment

Edwin Sutherland introduced a different perspective, rejecting the idea that crime results solely from internal defects. He emphasized that criminal behavior is learned through interaction with others. According to his theory of “differential association,” an individual becomes criminal when exposed to definitions that favor law violation more than those that oppose it.

In other words, the criminal mind is not born but shaped within a social environment that normalizes crime. Here, criminal thinking becomes a logical outcome of a certain value system, not merely individual deviance.

This raises an important philosophical question: if a person is a product of their environment, can they be judged absolutely? Or does society share responsibility in shaping this mind?

The idea that crime is learned opens the door to a broader understanding of culture’s role in shaping behavior. Every society defines what is acceptable and unacceptable, yet within it may exist “subcultures” with their own values that may conflict with dominant norms. In such environments, crime may not be viewed as deviant but as normal or even desirable.

Modern media also plays an increasing role in transmitting behavioral patterns, sometimes normalizing violence or glorifying criminal acts. This does not mean that everyone exposed becomes a criminal, but such influences help shape the framework within which thinking and behavior develop.

This perspective also highlights the importance of prevention, as crime can be reduced by improving social environments, promoting positive values, and providing healthy role models. The focus thus shifts from punishment to reform, and from the individual to society as a whole.

In this context, Robert Merton contributed with his “strain theory,” arguing that crime arises not only from learning but from the tension between socially imposed goals and the available means to achieve them. When individuals are expected to attain success without legitimate means, frustration emerges, pushing some toward alternative, possibly illegal paths. Here, the criminal is not merely a learner of deviance but an actor adapting to an unjust reality.

Similarly, Albert K. Cohen introduced the concept of “delinquent subcultures,” where marginalized youth create alternative value systems that invert dominant norms. In such cultures, rebellion may become virtue, violence a means of self-assertion, and success measured by defiance of the system. Thus, crime becomes not only a response to strain but an expression of collective identity.

Cloward and Ohlin further developed this perspective through the theory of “differential opportunity,” emphasizing that deviance depends not only on pressure but also on the types of illegitimate opportunities available. Not all frustrated individuals become criminals in the same way; paths differ depending on environment—organized crime, violent behavior, or withdrawal patterns—showing that the criminal mind is shaped by both deprivation and opportunity structures.


Fourth: Social Conflict and Crime as an Act of Resistance

From another perspective, Karl Marx viewed crime as a result of social inequality and class struggle. In this framework, some crimes can be understood as acts of resistance against an unjust system or reactions to marginalization and poverty.

Here, the criminal mind is not seen as sick but as conscious of its conditions, seeking—through illegitimate means—to achieve what it has been denied. This raises a bold philosophical question: Is every crime wrong, or can some crimes reflect deeper flaws in social structures?

This view highlights the political dimension of criminal behavior, where crime becomes a means of expressing rejection or rebellion. In unequal societies, individuals may perceive the system as unjust, leading them to challenge it unlawfully.

It also calls for reconsidering the definition of crime itself, as laws may reflect the interests of dominant groups, criminalizing actions not because they are inherently harmful but because they threaten the existing order.

However, this perspective carries risks, as it may justify serious crimes, requiring a careful balance between understanding social motives and preserving fundamental human values.


Fifth: Multiple Causation and the Complexity of Crime

Enrico Ferri attempted to reconcile these perspectives through his theory of “multiple causation,” arguing that crime results from a complex interaction of biological, psychological, and social factors.

According to this view, the criminal mind is not a simple entity reducible to a single cause, but the product of a network of influences, making it difficult to understand and even harder to predict.

This theory moves beyond the “either/or” approach, recognizing that reality is more complex. An individual may have biological predispositions, live in a difficult social environment, and undergo painful psychological experiences, all interacting to produce criminal behavior.

This complexity makes it difficult to establish a unified model, but it reflects the multidimensional nature of human beings. Thus, understanding the criminal mind requires a comprehensive approach that considers all factors without exclusion.

It also suggests that solutions must be equally multidimensional, combining punishment, psychological treatment, and social reform to achieve effective results.

Ferri’s approach reflects a deterministic philosophy, but it is not rigid. Instead of attributing crime solely to inherited traits, he acknowledged that individuals are influenced by their surroundings, life conditions, and broader societal structures. This multi-causal perspective allowed criminology to move closer to being a scientific discipline grounded in observation, analysis, and empirical research.

Anthropological Factors: The Individual Dimension

Anthropological factors refer to the biological and psychological characteristics of the individual. Ferri believed that traits such as age, gender, mental health, temperament, and inherited predispositions play a significant role in shaping behavior. However, unlike Lombroso, he did not claim that these factors alone determine criminality.

Rather, Ferri saw them as predisposing elements that may increase the likelihood of criminal behavior when combined with other influences. For example, a person with impulsive tendencies or psychological instability may be more vulnerable to engaging in crime, especially when exposed to adverse social conditions. This nuanced understanding helped bridge the gap between biological and psychological explanations within criminology.

Physical and Environmental Factors

The second category in Ferri’s framework includes physical or environmental factors. These refer to natural conditions such as climate, geography, seasonal changes, and population density. Ferri observed that certain types of crimes tend to occur more frequently in specific environmental contexts. For instance, violent crimes might increase during hotter seasons, while property crimes could be more prevalent in densely populated urban areas.

Although these factors may seem indirect, Ferri emphasized their importance in shaping human behavior. Environmental conditions can influence mood, stress levels, and social interactions, all of which contribute to the likelihood of criminal activity. By incorporating these elements, Ferri demonstrated that crime is not only a social or individual phenomenon but also one that is affected by the natural world.

Social Factors: The Most Influential Dimension

Among the three categories, Ferri considered social factors to be the most significant. These include economic conditions, education, family structure, cultural norms, and political systems. According to Ferri, society plays a crucial role in either fostering or preventing criminal behavior.

For example, poverty, unemployment, lack of education, and social inequality can create an environment where crime becomes more likely. Similarly, weak social institutions and ineffective legal systems may fail to deter criminal activity. Ferri argued that addressing these underlying issues is essential for reducing crime rates.

This perspective aligns closely with modern sociological theories, which emphasize the impact of structural inequalities and social disorganization. Ferri’s insights were remarkably forward-thinking, as they anticipated many of the concepts that would later become central to contemporary criminology.

Interaction Between Factors: A Dynamic Model

One of the most important aspects of Ferri’s theory is the idea that these factors do not operate in isolation. Instead, they interact in complex and dynamic ways. Crime, therefore, is the result of a combined effect, where each factor influences and reinforces the others.

For instance, an individual with certain biological predispositions (anthropological factors) may live in a disadvantaged neighborhood (social factors) and be exposed to harsh environmental conditions (physical factors). The convergence of these influences increases the likelihood of criminal behavior. This holistic approach allows for a deeper and more accurate understanding of crime, as it avoids reductionist explanations.

Prevention Over Punishment

A key implication of Ferri’s theory is the emphasis on prevention rather than punishment. If crime is caused by multiple interacting factors, then simply punishing offenders is not enough. Instead, efforts should be directed toward addressing the root causes of criminal behavior.

Ferri advocated for social reforms aimed at improving living conditions, education, and economic opportunities. He believed that by reducing social inequalities and enhancing the overall quality of life, it would be possible to prevent crime more effectively. This approach represents a shift from a purely punitive justice system to one that is more rehabilitative and preventive.

Criticism of the Theory

Despite its contributions, Ferri’s Theory of Multiple Causes has not been without criticism. Some scholars argue that the theory is too broad and lacks precise mechanisms for determining how each factor contributes to crime. Others suggest that it may underestimate the role of individual responsibility by emphasizing determinism.

However, these criticisms do not diminish the theory’s significance. On the contrary, they highlight the challenges of developing a comprehensive explanation for such a complex phenomenon. Ferri’s work remains a foundational reference point for ongoing debates in criminology.


Sixth: The Criminal Mind Between Freedom and Determinism

The fundamental philosophical question remains: Is the criminal free in their choice, or a victim of circumstances?
If we say they are free, we affirm full responsibility.
If we say they are compelled, we challenge the very concept of punishment.

The truth likely lies in between, where individuals possess some degree of freedom but operate within limits imposed by their environment and psychological makeup. Thus, understanding the criminal mind should aim not at justification, but at deep comprehension that enables prevention and treatment.

The debate between freedom and determinism is ancient, but in criminal psychology it gains special importance due to its connection to justice. If humans are not free, punishment becomes questionable; if they are entirely free, ignoring their circumstances becomes harsh.

Some philosophers propose that freedom is not absolute but “bounded freedom,” where individuals choose within contexts that shape their decisions. This offers a balanced view combining responsibility and empathy.

The criminal mind between freedom and determinism serves as a central axis for understanding how personal will can be influenced by biological and social conditions.

Ultimately, understanding the criminal mind from this perspective does not aim to justify crime, but rather to build a more humane system of justice that acknowledges human complexity and seeks not only to punish, but also to understand and rehabilitate.


Conclusion: How the Criminal Mind Thinks

The criminal mind is not an obscure mystery as much as it is a mirror reflecting the complexities of human nature. From Lombroso to Freud, and from Sutherland to Marx, interpretations vary, but one truth remains: crime is not an isolated event, but the result of a long process of internal and external interactions.

Understanding how the criminal thinks does not mean justifying their actions; rather, it means getting closer to the essence of humanity itself, with all its contradictions. Perhaps within this understanding lies not only an explanation of crime, but also a path toward a more just and humane society.
